It may be true that I can't stop and restart James through JMX (although
I hope I can), but this issue is more basic than that. I am unable to
query any of the JMX services registered by James. I have just changed
my code to try to interrogate the SMTPServer MBean and it behaves the
same way. I can get a list of attributes for the bean, but when I try to
query their value this exception is thrown:
[Spool Thread #5] [20 Mar 2007 07:54:36,250] ProcessingAlert [FATAL] -
fatal unexpected error in SMTPProcessor:javax.management.MBeanException:
Operation isEnabled not in ModelMBeanInfo
So, with all of James' JMX MBeans I can see the attributes and
operations, but am unable to check the values/execute the operation.
FYI, here's the code I've been playing with to interrogate the
"Application" MBean:
MBeanServerConnection connection =
JMXUtil.getMBeanServerConnection("jmxrmi");
String objName = "Phoenix:application=james,topic=Application";
MBeanInfo info = connection.getMBeanInfo(new ObjectName(objName));
SPLogger.debug(XTConstants.MODULE_APPLICATION, "JMX Object: " +
info.getDescription());
for (MBeanOperationInfo oper : info.getOperations()) {
SPLogger.debug(XTConstants.MODULE_APPLICATION, "Operation: " +
oper.getName());
}
for (MBeanAttributeInfo attr : info.getAttributes()) {
SPLogger.debug(XTConstants.MODULE_APPLICATION, "Attribute: " +
attr.getName() + "Value: " + connection.getAttribute(new
ObjectName(objName), attr.getName()));
}

Subject: Restarting James [Re: Exception while interacting with MBean]
Unfortunately, as far as I know, James cannot be restarted without
shutting down and restarting the JVM it runs in. To me, this does not
appear being a MBean-specific issue.
